Gallien Krueger Fusion 550

Also, when I first got it, a preamp tube broke in transit, so I just replaced the stock tubes (can't recall what they were) with a trio of JJs in the preamp. Plug and play and sounds awesome.

Pretty cheap upgrade that may really help. I never played the stock tubes, so i can't say if they were good or bad. All i know is the JJs I put in there sound great and it does look really cool with their location when they glow through the grill.
We use JJs for all our tubes.

I bought my GK 550 Fusion and 2 x 212 Neo cabs about 5 years ago. I used it twice, then stopped playing larger venues. The set- up has sat dormant since then (including through a 1,000 mile move). I recently had occasion to use it again, in an outdoor venue, and after 5 years of slumber in a semi- heated garage, I fully expected the pots to be dirty and the servo motors to bounce around, or worse. Instead, it fired right up and was rock solid through the entire gig — like brand new. I am totally impressed.
